Indigenous Knowledge and Ecology - The mistake of culture as timeless, knowledge as data Take a walk down Bourke’s main street and about midway, on the northern side, you will see a panoramic mural spanning the roofline of a simple brick building. It is a kind of timeline. At one end there is a panel devoted to Aboriginal life and Dreaming before colonisation, while the rest of the panels show a sequence of white exploration, pioneer settlement, a changing pastoral industry, reminders of historic floods, and a modern outback town....   [tags: Ecology] 914 words

The Role of Competition and Predation in Ecology - Competition and predation are two key factors that affect the stability of an ecosystem, such as a lake. There are three theories on the affects of competition. Competition may lead to competitive exclusion, stable coexistence, or niche differentiation. It has been shown that in marine environments, species are strong competitors for both light and nutrients and thus competition leads only to competitive exclusion (Passarge et al. 2006). The competitive exclusion principle states that if two species compete for the same resource in the same location, then one of those species will go extinct because one species will be the better competitor (Jenson 2010)....   [tags: ecology]

Maryland's Ecology and Environment - ... Since 1927 the commission has acquired over 13,300 acres of stream valley and river parks. These areas are used to protect natural resources, conservation, and education. Many of these water ways are considered ecological greenways. Before European settlers colonized parts of Maryland, the area was dominated by mixed hardwood forests. European settlers cut down native forests at a high rate and the timber was sold in Europe. These old growth forests are now virtually extinct in the state....   [tags: Ecology ]

The Impact of Sea Otters on Marine Ecology - ... Studies showed that the elimination of sea otters during the 1800s from the Californian waters might be responsible for the dwindling numbers of kelp forests. Further studies have also shown that the population density of sea otters affects seaweed biodiversity as well. In a study conducted in Alaska on three different bays, the Torch Bay, Deer Harbor and the Surge Bay, it was found that the presence of sea otters led to a decrease in the population of sea urchins, which led to an increase in the population of seaweeds....   [tags: Ecology ]

Theories of Social Ecology - ... "The right of all forms [of life] to live is a universal right which cannot be quantified. No single species of living being has more of this particular right to live and unfold than any other species" (Naess, 1995, Reader p. 68). Deep ecology was also modeled after Naess’ view. Deep ecology is an ecological philosophy which recognizes the inherent worth in nature rather than its utility. Echoing this view, all life forms whether human or non-human deserve the right to live and to flourish. When we destroy, transform, preserve, and renovate the well-being, flourishing, richness, and diversity of nature (Naess, p....   [tags: Social Ecology]

The process plays a much more important role than it is usually credited with. Bioeroding species, consisting of many different types of organisms that act on the environment in a seemingly endless variety of ways, interact with the ecosystem and with each other as part of the reef growth and degradation cycle. The degradation portion of this cycle, the part that is most often overlooked, is essential for the development of reefs as the diverse and beautiful habitats that we know them as....   [tags: Bioeroding Ecosystem Ecology Essays]

While many other studies have stressed the lethal effects of predation by carnivores, the authors of this study have chosen to focus on how nonlethal outcomes of predation affect the structure and function of ecosystems. The authors give two main objectives to their study: first to provide a short synthesis of the potential ecosystem responses to predation risk in a three-level trophic cascade involving large carnivores, hoofed animals, and vegetation; and secondly to present research that centers on wolves, elk, and woody browse species in the northern area of Yellowstone National Park....   [tags: Ecology] 744 words

Deep Ecology - Deep Ecology/Ecosophy The ideas behind deep ecology have major implications today. They allow people to think more profoundly about the environment and possibly come to a better understanding of their own meaning. People are intensely concerned about the world’s technological adolescence, massive consumerism, and overpopulation. A man named Arne Naess, former head of the philosophy department at the University of Oslo founded an idea that can direct people’s anxiety away from their "shallow" notion of the problem to one that is much "deeper." "Deep ecology goes beyond the limited piecemeal shallow approach to environmental problems and attempts to articulate a comprehensive religious and philosophical worldview."

Protecting the Daintree Rainforest - 1. Destroying the habitat of different plants and animals, they no longer have a place to live. Their food source and nutrients are taken away and have nowhere else to go. These organisms will die out and there will be a loss in the diversity of that ecosystem. That ecosystem can then start to crumble as the habitats are taken away and the plants and animals have no home. With no habitat in which the organisms can live in, there is going to be very little diversity. 2. a) The Daintree rainforest at Cape Tribulation, in far north Queensland is diverse in many ways....   [tags: Ecology]

This study investigates contrasts floral and invertebrate diversity between kānuka and gorse (Ulex europaeus), a plant which has been used elsewhere as an efficient primary successional shelter, and as an equivalent harbour for invert diversity. Six stands, three of gorse, three of kanuka, were sampled using transects totalling five samples per stand. The stands measured were too immature to support understory, but kānuka was significantly more diverse in invert fauna than gorse....   [tags: Ecology]

Wetlands - We chose to research about wetlands because they are very unique and special. Wetlands used to be extremely common during prehistoric times, but now there are only small areas left. Some plants and animals exist only in the wetland biomes, such as the star fruit and water vole. But, as the amount of wetlands decreased, many organisms became endangered and even extinct. We wanted to find out more about what the characteristics of wetlands and what is being done to help the environment. A wetland is an area where the ground is soaked or underwater for most of the year....   [tags: Ecology]

Insecticidal Efficacy - Hussein (1991) reported that the use of Tween-80 and Span-80 surfactants as synergistic agents had improved the insecticidal efficacy and lowered the LC50 values from 3.3 to 5 times in case of Cyphenothrin and from 3.2 to 5.7 times in case of fenitrothion. Tween-80 was found more effective than Span-80. The combination ratios between the insecticides and the surfactants are important in determining the insecticidal efficacy. Abdel-Rahman et al. (1995) evaluated the toxicological effects of five different insecticides (Propoxur, Fenitrothion, D-Phenothrin, Malathion and Permethrin) separately and in combination with two surfactants (Triton X-100 and Tween-20) on Culex pipiens larvae....   [tags: Ecology] 2282 words

This area is within Australia’s Exclusive Economic Zone but is more than 4,000 kilometers from the nearest port, thus placing it far beyond the range of regulators and law enforcement. The area is also within the Southern Ocean, which falls under international legal frameworks, specifically the Convention on the Conservation of Antarctic Marine Living Resources and the United Nations Convention on the Law of the Seas....   [tags: Ecology]
